What I was thinking about was a WSDL wrapper around the AdminCommandsServiceMBean methods. I'm currently investigating the WSN component to use it for notifications based on message content (see http://www.nabble.com/how-to-implement-runtime-notifications-based-on-Me ssageExchange--content-tf3409844s12049.html), but I must say I'm afraid I don't really understand your idea (which may be due to my limited experience with jaxb2). It seems to me that the wsn component WSNEndpoint uses the annotations done in the org.apache.servicemix.wsn.AbstractEndpoint hierarchy (an object of this class is passed in as "pojo" in the constructor) to obtain a class object "endpointInterface" which is then used to get hold of the methods published in that interface. Jaxb2 seems to be used to unmarshal incoming normalized message content and to marshal it to outgoing exchanges (method: process). However, if I'm ""only"" writing a provider service and not a full-fledged component, what would be the advantages of the approach taken in WSNEndpoint? Or am I misinterpreting, and you're using jaxb2 for creating a jsr181 code skeleton based on a previously generated WSDL?
Yeah, that's the point. The WSNEndpoint is used to invoke an annotated POJO generated from the WSDL like AbstractNotificationBroker. The AbstractNotificationBroker#init method calls register, which ultimately creates a WSNEndpoint with the AbstractNotificationBroker class as the pojo. So, once the WSDL is written, you can use wsgen to generate the interfaces and messages, create your own POJO implementation and wrap it with the WSNEndpoint. (It makes me think that this class may be put in servicemix-common). But this is only one way to do that. Feel free to use your own if you prefer. The last question is how do we package that. I'm thinking about a SE, but without any support for deployments of SU, I guess another way could be to leverage the JSR181 component and just write a SU for it (and another for the http BC i guess). The last way would be to configure it directly on the JBI container without any JBI packaging ... Need to think about pros / cons ...
.. and discussions about servicemix developement should take place on the > dev > list ... ;-) Done :-)
